Summer Tick Season: The 24-Hour Check That Works

Tick season in temperate regions runs from April through October, with a smaller second peak in September, and the check that matters happens within 24 hours of the cat coming back inside. Most pathogens a tick carries need a day or two of attachment before they reach the bloodstream, so a tick found and pulled the same evening is usually a tick that injected nothing. The rest of the routine is smaller than owners expect: three spots that hide ticks, one preventive schedule that survives frequent bathing, and a 3-week watch for fever.

Why the 24-hour window beats counting ticks

A tick does not bite and inject in one motion. It cuts into the skin, cements itself with saliva, and feeds for 3 to 10 days depending on species and life stage. The bacteria behind anaplasmosis and ehrlichiosis sit in the midgut and migrate to the salivary glands only after hours of feeding; Lyme transmission, the best studied of the group, generally needs 24 to 48 hours. A flat 2 to 3 mm tick has been attached less than a day. A grey, engorged one has been there 5 days or more.

Indoor-only cats are not exempt. Ticks arrive on dogs, on shoes, and on cut grass carried inside, and a fair share of infested cats in household surveys never go out. Nymphs measure 1 to 2 mm and look like a freckle or a scab, which is why the check needs fingers as much as eyes.

Three blind spots: ear, armpit, between the toes

Ear: lift the pinna and look at the skin at the base of the canal and in the fold where the ear meets the skull, not down the canal. A tick there reads as a dark crust that does not brush off. Armpit: the thin-skinned hollow behind the front leg, found by pressing two flat fingers forward. Toes: spread the pads and check between toes 3 and 4 and around the dewclaw, where ticks lodge after a walk through grass. A spring coat makes this harder, and the shedding and hairball routine covers how to comb out the mats that hide a feeding tick.

Run both hands against the coat over the whole body, 5 to 10 seconds per zone, about 3 minutes for a medium cat, then finish with a fine-toothed comb on short hair. Head, neck, and front legs come first because grass passes them at nose height.

Removal that leaves no mouthparts behind

Use fine-tipped tweezers, grip as close to the skin as possible, and pull straight up with steady pressure for about 5 seconds. Do not twist, do not squeeze the body, and do not apply alcohol, oil, or a match first; those irritate the tick and raise the odds it regurgitates into the wound. Disinfect with chlorhexidine and leave the site alone. If mouthparts stay embedded, do not dig. The skin usually expels them, but a red, swollen, or discharging spot needs a vet within 24 to 48 hours.

Keep the tick in a sealed bag or a vial of 70 percent alcohol labeled with the date and the body location. If the cat is ill 2 to 3 weeks later, the species tells the vet which diseases are plausible.

When the bath schedule fights the preventive

Fipronil spot-on products spread through the skin's oil layer, and shampoo strips that layer. The label on most cat products calls for no bathing for 48 hours before or after application, and washing more often than every 2 weeks shortens protection well before the 4-week redose date. If the cat needs a medicated bath for a skin condition, apply the spot-on 48 hours after the bath, not before, and note the date.

Oral isoxazolines avoid the conflict: fluralaner is redosed every 12 weeks and sarolaner or afoxolaner every 4 weeks, and neither is affected by shampoo once the tablet is absorbed, which takes about 2 hours. Give fluralaner with a meal; absorption drops sharply on an empty stomach. Imidacloprid and flumethrin collars last 8 months and tolerate a bath, but not scrubbing at the neck, and they need to sit snug with room for two fingers.

One hard rule: never put a permethrin dog product on a cat. Concentrates of 45 to 65 percent permethrin cause tremors and seizures within hours, and it is the most common spot-on poisoning seen in cats. If it happens, bathe with dish soap and call a vet or a poison line.

Two to three weeks of watching

Mark the date. Normal feline temperature is 38.1 to 39.2 C, so a reading above 39.5 C counts as fever. Watch for lethargy lasting more than a day, refusing food for 24 hours, pale or yellow gums, hind-leg weakness, joint swelling, or labored breathing. A single tick bite with no symptoms does not require bloodwork; symptoms do, and the panel is a CBC plus a tick-borne disease PCR.

Weight moves the dose, and a 1 kg gain over a slow autumn is enough to leave a cat underdosed on last year's pipette, which is the argument for weighing monthly; the autumn weight check explains what a normal seasonal gain looks like. If you already log intake, the daily portion calculator gives a fixed number to adjust against.

Summer checklist

1. Check ear, armpit, and toes within 24 hours of any trip through grass, 3 minutes total.
2. Write the tick date and body site on the bag and recheck the site for 3 days.
3. Put the next redose date in the calendar with the 48-hour bath blackout on it.
4. Weigh the cat monthly from May to October and recheck the dose at a 0.5 kg change.
5. Call the vet for fever above 39.5 C, pale gums, or hind-leg weakness, not for one flat tick.
